ON±VEHICLE INSPECTION (2VZ±FE)
SPARK TEST
CHECK THAT SPARK OCCURS
(a) Disconnect the high±tension cord from the distributor.
(b) Hold the end approx. 12.5 mm (0.50 in.) from body of vehicle.
(c) See if spark occurs 'while engine is being cranked.
HINT: To prevent gasoline from being injected from injectors
during this test, crank the engine for no more than 1
± 2 seconds at time.
If the spark does not occurs, perform the test as follows:
CHECK RESISTANCE OF IGNITION COIL
(See page IG±12)
Resistance (Cold):
Primary 0.41 ± 0.50

Secondary 10.2 ± 13.8 k
CHECK POWER SUPPLY TO IGNITION COIL
1. Ignition switch turn to ON.
2. Check that there is battery voltage at
ignition coil positive (+) terminal.
CHECK RESISTANCE OF SIGNAL
GENERATOR (PICKUP COIL) (See page IG±8)
Resistance: 140 ±180
CHECK RESISTANCE OF HIGH±TENSION
CORDS (See page IG±10)
Maximum resistance: 25 k
per cord
CHECK AIR GAP OF DISTRIBUTOR
(See page IG±12)
Air gap: 0.2 mm 10.008 in.) or moreCHECK CONNECTION OF IGNITION COIL,
IGNITER AND DISTRIBUTOR CONNECTORS
Check wiring between ECU and distributor,
only then try another ECU.Check wiring between ignition switch to
ignition coil.
CHECK IGT SIGNAL FROM ECU
(See page FI±62)Replace the ignition coil.
Replace the distributor.
TRY ANOTHER IGNITERReplace the distributor. Replace the cord(s). Connect securely. SPARK TEST

GENERAL REPAIR INSTRUCTIONS
1. Use fender seat and floor covers to keep the vehicle clean
and prevent damage.
2. During disassembly, keep parts in the appropriate order to
facilitate reassembly.
3. Observe the following:
(a) Before performing electrical work, disconnect the neg-
ative cable from the battery terminal.
(b) If it is necessary to disconnect the battery for inspection
or repair, always disconnect the cable from the nega-
tive H terminal which is grounded to the vehicle body.
(c) To prevent damage to the battery terminal post, loosen
the terminal nut and raise the cable straight up
without twisting or prying it.
(d) Clean the battery terminal posts and cable terminals
with a shop rag.
o not scrape them with a file or other
abrasive objects.
(e) Install the cable terminal to the battery post with
the nut loose, and tighten the nut after installation. Do
not use a hammer to tap the terminal onto the post.
(f) Be sure the cover for the positive (+) terminal is properly
in place.
4. Check hose and wiring connectors to make sure that they are
secure and correct.
5. Non±reusable parts
(a) Always replace cotter pins, gaskets, 0±rings and oil
seals etc. with new ones.
(b) Non±reusable parts are indicated in the component il-
lustrations by the ºrº symbol.
